Take the new one back and rely on the old one, but put it on a level surface. Mine is in the carpeted bedroom (the bathroom is too tiny) and it's on a piece of plywood that is just an inch or so bigger all around than the scale. If you still think the results are erratic, go rebuy the new scale. I'd try the plywood under the old scale first. If I move my scale from room to room, where there are different thicknesses of carpet, I can get as much as a 20 pound difference. The thicker the carpet, the less I weigh!
